Yeah, and I'd say RPGs are the best genre for learning. They have both lots of text and keep you addicted for long periods of time. And when you point with the mouse at, say, a broom and the word for "broom" flashes up, that helps a lot.
There are also kanji learning games for Japanese children, but from what I've seen so far (I've played Doraemon The Kanji Study Boy or something like that, for gbc) they're of no use for me other than maybe for stroke-order. They naturally assume the player to know the words, just not the symbols. And aren't all that fun either.
